Question:
I have a 2004 Ranger Trail boat trailer. I am looking to replace the rotor, hub, bearings and seals. I measured the rotor at 9.75 and there are 5 lugs. I also have oil bath hubs. The fill hole for the bearing oil is a threaded hole with a plug on the nose part of the hub that protrudes from the center. I noticed on the Part Number: K08-435-05 there is no threaded hole. Is there a hub with the fill hole? I did see Kodiak XL ProLube Kit for for 5,200-lb to 6,000-lb Axles. I think I have Dexter 3500 lb axles and I have the DB-35 disc brakes. Not sure the Kodiak system will work. If you would like, I can send you some pics of my hub and oil bath hubs. Thanks

Hey Richard, thanks for reaching out!
It sounds like you're needing the Kodiak Disc Brake Kit # KOD77FR which comes with new hubs/rotors, matching calipers, and the oil bath parts.
In order to fill the oil hubs you'll have to remove the black plug from the cap, but that's pretty standard for oil bath kits.
Does this look like a good replacement to you?

Just one question. Per the video it says I should have an actuator and brake lines rated at 1500 PSI or above. Would this be marked on the master cylinder or brake lines on my trailer?
